Linus Torvalds 80b29b6b8c csky-for-linus-5.4-rc1: arch/csky patches for 5.4-rc1 
This round of csky subsystem just some fixups.
 
 Fixup:
  - Fixup mb() synchronization problem
  - Fixup dma_alloc_coherent with PAGE_SO attribute
  - Fixup cache_op failed when cross memory ZONEs
  - Optimize arch_sync_dma_for_cpu/device with dma_inv_range
  - Fixup ioremap function losing
  - Fixup arch_get_unmapped_area() implementation
  - Fixup defer cache flush for 610
  - Support kernel non-aligned access
  - Fixup 610 vipt cache flush mechanism
  - Fixup add zero_fp fixup perf backtrace panic
  - Move static keyword to the front of declaration
  - Fixup csky_pmu.max_period assignment
  - Use generic free_initrd_mem()
  - entry: Remove unneeded need_resched() loop
